MITER-BOX.

Specification of Letters Patent. Patented July 20, 1915.

Application led March 25, 1914. Serial No. 827,190.

To all-whom t may concern j Be it known that I, EARL ROY FoUsT, a citizen' of the United States, residing atl Flandreau, in the county of Moody. and State of South Dakota, have invented oertain new and useful Improvements in MiterA Boxes, of which the following is a. specifica-y tion, reference being had to the accompany-` ing drawings.

This invention relates to certain improve-Y ments in miter boxes and has relation more particularly to a device of thisgeneral character wherein the saw guide or frame is capable of adjustment to produce the requisite angles; and the object of the invention is to provide a device of this generalchar` acter having novel and improved means whereby the saw guide or frame maybe eifectively maintained in its various adjust.- ments and wherein the saw proper may be `adjusted with convenience and facility relative to the work, as the necessities of practice may require. j Y

The invention consists in the detailsof construction and in the combination and ar'- rangement of the several parts of my improved miter boX whereby certain important advantages areattained and the device is rendered simpler, less expensive and other- -wise more convenient and advantageous for use, all as will be hereinafter more fully set forth. j

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be Vthe better understood, I will nowproceed to describe the same with reference to the accompanying drawings, whereinl Figure 1 is a front elevational view of a miter bon constructed in vaccordance with my invention; Fig. 2 is a transverse vertical sectionalvview taken substantially through the center of Fig. 1; Fig. 3 is a view in top plan of the'device as illustrated in Fig. 1, with certain ofthe parts shown in section; Fig. lis a sectional view taken substantially on the line 4 4 of Fig. 3; Fig. 5 is a fragmentary view, partly in elevation and partly in section, illustrating the block herein included, atv the side opposite to that .shown in Fig. 2; Fig. 6 is a fragmentary sectional view illustrating in rear elevation the depending disk herein included; and Fig. `7 is an enlarged fragmentary View, partly in sect-ion and partly in elevation, illustrating the mean-s for maintaining the saw guide in an elevated position.

As disclosed inthe accompanying' drawings, 1 denotes a work. table of any ordinary or preferred construction having its intermediate portion cut away, as at 2, as is generally done inl devices of this character, and 3 denotes the back plate also out away, as indicated ate, in a conventionalmanner. The side .member 5 of the work table has mounted thereon for rotation about avertical axis, a lbearing @while `the opposite side member 7 of the work table is provided with a 'forwardly projected member 8, such member constituting asegment of a circle circumscribed around the axial center of the bearing 6. Positioned below4 the member 8 and adapted to move relatively thereto is a vblock 9 provided at its rear face with an upstanding arm 9a having its upper extremity angularly disposed and overlyingthe upper'face of the member 8 and terminating ina bearing 10. By this arrangement, it-

will -be seen that the arm 9a' serves as a supporting medium for the block 9. In order to maintain the block against movement laterally of the member 8, I also provide said block 9 with an upstanding ,arm 9b overlying'the forward. edge lof the4 member 8, as is `believed to be particularly shown in Fig. 2 of the accompanying drawings.

The bearings 6 andl l0 have rotatably mounted therein, the lower connecting bar 11 ofthe tubular posts 12, such bar 11 being preferably circular in cross section and adapted to have its upper portion substanj tially flush with the upper surface of the work table 1 when in operative position, and is .provided with the longitudinal groove or recess 14 of predetermined'depth adapt` ed to accommodate the `cutting edge or teeth of the saw in order tof prevent such cutting edge or teeth from becoming injured after conventional saw may be employed, the upper extremity of such slot is enlarged, as indicated at 18.

rfhe member 8 is adapted to determine the horizontal angle at which the work is to be cut and in order that the angle may be determined with convenience and facility, l produce on the upper face of the member' 8 the desired graduations, as indicated at 19, while l produce on the under surface of the member 8 the transverse or radial grooves 20 in vertical alinement with the graduations 19 and which grooves are adapted to accommodate the peripheral portion of the cam member 21 pivotally engaged with the block 9 at a point below the member S and which is adapted to so bind against the under surface of the rack 8 as to effectually hold or clamp the block 9 in its adjusted position.

ln order to determine the requisite vertical angle of a cut, the bar 11 has depending therefrom in advance of but in close proximity to the member 8, the segmental disk 22 having the desired graduations 23 produced on the 'marginal portions thereof and having produced in its periphery in substantial register with the graduations 23 the notches or recesses 24 which are adapted to accommodate the peripheral portion of the cam member 25 operatively engaged with the face of the block 9 opposite to the face to which the cam 21 is connected. By this arrangement, it will be seen that the proper vertical adjustment of the saw will be effectively maintained. l also find it of advantage to have the lower forward portion of the block 9 provided with a recess or channel 26 in which the periphery of the segmental disk 22 is adapted to extend and to have such portion of the block provided with the upstanding stationary pointer or index adapted to cooperate with the graduations 23 on the disk 22.

ln order that the depth of the cut may be controlled or limited, l find it of advantage to have threaded vertically through the heads 27 of the saw guides 17 the screws 28, the lower extremities of which being adapted to contact with the upper ends of the posts 12 and operating in a manner which is believed to be self-evident.

lt often occurs in practice that it is especially desirable to maintain the saw in an elevated or lifted position and, as herein disclosed, I provide for this purpose a springcontrolled latch 29 suitably secured to an outer face of each of the posts 12 and having an extremity thereof provided with an inwardly directed pin 30 adapted to normally engage a recess or pocket 30a formed in the post 17 adjacent the lower extremity thereof.

rlhe controlling spring 31, as herein disclosed, is disposed about the elongated member 32 normally projected through the opposite extremity of the latch 30 and having its outer extremity adjustably engaged by the stop 33, herein shown as a conventional nut in threaded engagement with such member, which serves a means to positively hold the latch in such position as to maintain the inwardly directed pin thereof in retracted position.

From the foregoing description, it is thought to be obvious that a miter box constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and by reason of the effectiveness with which it performs its functions, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

1. A device of the character described comprising a work table, a segmental member projecting forwardly therefrom, a block positioned below the segmental member, the rear face of said block being provided with an upstanding angular arm overlying the upper face of the segmental member and affording a suspending means for the block and permitting the same to be moved independently of the segmental member, a bar mounted for swinging movement on said work table and capable of axial rotation, said bar being also rotatably mounted in the upper extremity of the angular arm of the block, and locking means carried by the block coacting with the segmental member for maintaining the block in different adjpstments relative to the segmental mem- 2. A device of the character described comprising a work table, a segmental member projecting forwardly therefrom, a block positioned below the segmental member, the rear face of said block 2being provided with an upstanding angular arm overlying the upper face of the segmental member and affording a suspending means for the block and permitting the same to be moved independently of the segmental member, a bar mounted for swinging movement on said work table and capable of axial rotation, said bar being also rotatably mounted in the upper extremity of the angular arm of the block, and locking means carried by the block coacting with the segmental member for maintaining the block in different adjustments relative to the segmental member, said block being also provided with an upstanding arm overlying the forward face of the segmental member and serving to maintain the block against movement transversely of the segmental member.

3. A device of the character described comprising a work table, a segmental member projecting forwardly therefrom, a block positioned below the segmental member, the rear face of said block being provided with an upstanding angular arm overlying the upper face of the segmental member and aording a suspending means for the block and permitting the same to be moved independently of the segmental member, a bar mounted for swinging movement on said work table and capable of axial rotation,

said bar being also rotatably mounted in the upper extremity of the angular bar of thev block, locking means carried by the block coacting with the segmental member for maintaining the block in different adjustments relative to the segmental member, and ooacting means carried by the bar and the block for holding the bar against axial rotation.

In testimony whereof I hereunto yaffix my signature in the presence of two witnesses.
